Description

UNITED STATES PATENT OEEIoE.

GEORGE A. REYNOLDS, OF ROCHESTER, NEW YORK.

IMPROVED FRUIT-JAR.

Specification forming part of Letters Patent No. 58,674, dated October 9, 1866.

To all whom 'it may concern.'

Be it known that L'GEoRGE A. REYNOLDS, of Rochester, in the county of Monroe and State of New York, have invented a new and useful Self-Sealing.Fruit-Jar, and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, mal;- ing part of this specification, in which- Figure 1 is an elevation of a fruit-jar having my invention attached, a portion ofthe top of the jar being broken away, and the conical cover O shown in central section. Fi g. 2 is a top view of the packing and clamping iiange or ring i' ofthe top of the jar. Fig. 3 is a transverse central section of the clamping-bar R, as indicated by the red line o in Fig. 1.

Like letters indicate corresponding parts in all the figures.

This invention relates to thatclass of selfsealing jars which have metallic covers and clamping-bars, and it consists in providing a small vent-hole at the top or apex ofthe cone, to permit the escape of the hot air from the lled jar after the cover is placed in position, and previous to the application of the clamping-bars, which is provided with a suitable packing-button, to seal this vent-hole.

To enable others to make and use my invention, I will describe its construction and operation.

The top of the jar J is provided with a shoulder, s, for the annular packing to rest upon, and a projecting rim or tlange, o, portions ot' which are broken away, as shown at a, Fig. 2, to receive the hooks c of the clampingbar B 5 or, instead of the ring, there may be two oblong or oval-shaped lugs arranged on opposite sides of the top.

The ends of the clam pin g-bar should be made quite broad, so that the inclined planes which constitute the hooks c shall afford the desired draft without being too steep.

The bar is provided in the center with a recess, (shown at n, Fig. 3,) into which the rubber packing-button t is inserted.

The metal tops or covers C may be punched out and struck up with dies, and they should be provided with a small orifice at the center or apex, and the edge should be contracted somewhat as shown in Fig. 1, so that it should rest upon the annular packing t', nearly at right angles with the plane of the top.

After the jar is filled, the ring i is placed on the top of it and the cover C adjusted. The clamping-bar B should not be applied under a few seconds, until the hot air and gases have time to escape without straining the packing, Smc., and as soon as the escape ceases, or even before, with this arrangement the clamp is placed with the packing-button t upon the opening in the cover, and then turned so as to eft'ectually close that joint and the one at the edge of the cover at the same time.

Great difficulty has been experienced in p reventing the covers of the self-sealin g jars from being loosened bythe outward pressure before the temperature of the contents should become sufficiently reduced to cause the atmospheric pressure to counterbalance it. Various plans have been proposed, all of them more or less intricate, to obviate this difculty. The object seems to be fully and effectually accomplished in this invention, which is' extremely simple and cheap.

The covers may be made spherical instead of conical, it desired, and also of glass.

W' hat I claim as my invention, and desire to secure by Letters Patent, is-

The arrangement of the clamping-bar B, having the inclined planes or hooks c formed upon its ends, and provided in the center with a iiXed elastic packing, t, for the vent formed in the apex of the cover in this class of selfsealing cans or jars, as and for the purpose shown and described.
